Do nuclear weapons promote peace?

Pro

Nuclear deterrence. Nuclear weapons are known to have protected peace, rather than the opposite. In the military, there's a rather famous doctrine called MAD (Mutually Assured Destruction). This doctrine theorizes that since nuclear weapons cause enormous damage, would alert the target and that the target would also fire nuclear weapons, no country would be mad enough to attack countries with nuclear weapons. Also, if nuclear weapons were really that dangerous, the world would have been most probably destroyed during the Cold War. It was because of the danger of nuclear weapons that countries couldn't invade nor fire nukes on each other.
